Ранее я делал серию постов про битовые операторы. Вот вам ещё один наглядный пример как это используется в Python в модуле re. Чтобы указать флаг для компилятора нам надо указать его после передаваемой строки. Например, добавляем флаг для игнорирования переноса строки. pattern = re.compile(r"(\w+)+") words = pattern.search(text, re.DOTALL) А как указать несколько флагов? Ведь явно будут ситуации когда нам потребуется больше одного. Кто читал посты по битовые операторы уже понял как. pattern.search(text, re.DOTALL | re.VERBOSE) А теперь смотрим исходники, что находится в этих атрибутах? Не удивительно, степени двойки. Почему? Потому что каждое следующее значение это сдвиг единицы влево. >>> for n in [1, 2, 4, 8, 16, 32, 64, 128, 256]: >>> print(bin(n)) 0b1 0b10 0b100 0b1000 0b10000 0b100000 0b1000000 0b10000000 0b100000000 Чтобы было понятней, давайте напишем тоже самое но иначе, добавим ведущие нули: 000000001 000000010 000000100 000001000 000010000 000100000 001000000 010000000 100000000 Не понятно что тут происходит? Читай три поста про битовые операторы начиная с этого ➡️https://t.me/pythonotes/45 В общем, это пример применения побитовых операций в самом Python. Теперь вы знаете Python еще немного лучше) #tricks#regex#libs

🚘 Cybercab announced: Elon Musk’s robotaxi is finally here 📍 Tesla boss Elon Musk has unveiled the firm's long-awaited robotaxi, the Cybercab, at the Warner Bros Studios in Burbank, California. 🚕 The robotaxi is a purpose-built autonomous vehicle, lacking a steering wheel or pedals, meaning it will need approval from regulators before going into production. The design was futuristic, with doors that open upward like butterfly wings and a small cabin with only enough space for two passengers. There was no steering wheel or pedals, nor was there a plug — Musk said the vehicle charges inductively to regain power wirelessly. 🚐 In a surprise, the company also revealed a "robovan," a self-driving van capable of carrying up to 20 passengers or being configured for cargo purposes. 🪙 Musk said that autonomous cars are expected to be 10–20 times safer than human-driven vehicles and could cost as little as 20 cents per mile, compared to the $1 per mile for city buses. @CarsNews #Tesla#driverless

New 🚘 electric cars will get Chinese autopilot It will be developed by startup Momenta and will debut on the CLA electric sedan. The hardware will be based on Nvidia's Orin X chip. The all-electric CLA will be equipped with a high-level intelligent driving system that does not rely on high-definition maps. This advanced system will provide navigation in the city, and mass production of the electric car is scheduled for April 2025. Mercedes-Benz is one of Momenta's investors, along with GM and SAIC. @CarsNews #Mercedes#EV#driverless

🚕Waymo robotaxis are back at the center of a scandal 📍 This time, the vehicles caused chaos on the streets of San Francisco. 🚥 The autonomous taxis use the traffic-light system for navigation, so when it goes down, route planning breaks as well. ⛔ For several hours, Waymo cars stood on the roads like bricks, blocking other drivers from getting through. Is rise of the the machines beginning? #driverless#incidents@Car_News

😰Three Waymo robotaxis caused a “standoff” and blocked a street in San Francisco 📰 In the northern part of San Francisco, three Waymo autonomous taxis got stuck on a narrow street, completely blocking traffic. Two cars lightly collided while trying to maneuver, after which both went into emergency mode, and the third stopped right in front of them, creating a full traffic jam. 😤 Because of this, residents couldn’t leave their driveways and had to wait for company engineers to intervene and resolve the situation. All vehicles were empty — no passengers were inside. 💬 Waymo commented on the incident, calling it a “learning moment” for improving their autonomous driving system. #driverless#incidents@Car_News
